shadowmere will respawn, according to the creation kit tags for shadowmere. check back at the dark brotherhood sanctuary in falkreath

If she does respawn then thats the last time Im pulling a hannibal. spent like 5k on horses so far cuz dragons seem to target them

Maybe mammoths would fare better. Hannibal used elephants when he invaded the Roman Republic. I guess we could use mammoths. You could also modify Shadowmere in the Creation Kit by setting her to essential.

yeah she hasnt respawned yet and its been like 2 or 3 in game weeks already

You been back to the place where you originally found her?

Yeah I even waited a few days where she died and where she spawned from and she is perma dead from falling off a mountain. I dont remember where the body is anymore because its been like 3 days since I bought the game so if shes revived shes somewhere far to the north. also If she did revive she shouldve probably spawned by me when I fast travel isnt she?
